In Philadelphia on a dreary "spring" day in 2007, I saw what I believe to be one of the most impressive mullets in the world.
Since I (sadly) don't carry a digital camera all the time, I must describe it (Google Images won't yield anything even close):
20ish male with dirty blond curly-ish hair about 2 inches long
from the front: a bad lack of haircut/semi-mop, as is popular with the college-aged artsy and/or trendy set
from the back: waist length dreadlocks...but only from the region that at one point in time would have been used to create a tail...
